The processor 120 may identify bending state information including area segmentation information of the flexible display 260 corresponding to a bending degree of the flexible display 260, using the bending sensor 660. For example, the bending sensor 660 may be configured such that flexible sensors capable of measuring the bending degree of the flexible display 260 are usable in combination with the flexible display 260. For example, the bending sensor 660 may include at least one of a flex sensor, a pressure sensor, at least one inertial sensor (e.g., a gyro sensor and/or an acceleration sensor), or a Hall effect integrated circuit (IC) sensor.

The processor 120 may determine a first display area of the flexible display 260 based on the wearing state information and/or the bending state information. For example, the processor 120 may identify segmented areas of the flexible display 260 based on the bending state information. In addition, based on the wearing state information, when the electronic device 101 is being worn, the processor 120 may identify the position of the user's body on which the electronic device 101 is being worn and the orientation in which the electronic device 101 being worn on the user's body is worn. For example, when it is identified that the electronic device 101 is being worn on the user's left arm, the processor 120 may determine, as a first display area, areas corresponding to a position where a user's gaze is directed to the left from among the segmented areas of the flexible display 260. Alternatively, when it is identified that the electronic device 101 is being worn on the user's right arm, the processor 120 may determine, as a first display area, areas corresponding to a position where a user's gaze is directed to the right from among the segmented areas of the flexible display 260.

The processor 120 may display first object information on the first display area of the flexible display 260. For example, the first object information may include a watch face screen, a user interface screen, and a display screen showing various contents. The first object information may include a screen configured to have a size or orientation suitable for serving as the first display area. For example, when the first display area includes a wide area in the entire area of the flexible display 260, the processor 120 may display first object information including a screen corresponding to the wide area. Alternatively, when the first display area includes a narrow area in the entire area of the flexible display 260, the processor 120 may display first object information including a screen corresponding to the narrow area. Alternatively, when the electronic device 101 is worn on the left arm of the user, the processor 120 may display first object information including a screen that is useful when a user looks in the left direction. Alternatively, when the electronic device 101 is worn on the right arm of the user, the processor 120 may display first object information including a screen that is useful when the user looks in the right direction.

The processor 120 may, in response to identification of a situation change of the electronic device 101, display second object information on a second display area including at least a partial area of the first display area of the flexible display 260, based at least on situation information of the electronic device 101 and/or posture information of the electronic device 101.

The processor 120 may identify situation information of the electronic device 101 based on a pattern of collected sensor data or learning thereof, using at least one sensor included in the sensor module 176. The processor 120 may identify situation information related to a behavior pattern of a user wearing the electronic device 101, based on a pattern or learning of sensor data collected by at least one of a gyro sensor, a magnetic sensor, or an acceleration sensor included in the sensor module 176. For example, the situation information may include at least one of stopping, walking, running, riding a bicycle, driving a vehicle, or exercise using the arms as a user's behavior pattern. The processor 120 may identify whether a previous situation changes to a preconfigured situation based on the situation information of the electronic device 101. For example, the processor 120 may identify that the situation of the electronic device 101 has changed when the previous situation information and newly identified situation information are different from each other. Further, when it is identified that the situation, which has been changed based on the situation information of the electronic device 101, is maintained for a preconfigured time, the processor 120 may identify that the situation of the electronic device 101 has changed. For example, when the identified previous situation information indicates a stopped state and the newly identified situation information indicates a vehicle-driving state, it may be identified that the situation of the electronic device 101 has changed. For example, a situation in which the arm of a user wearing the electronic device 101 is maintained in a fixed state at a predetermined angle and the user's gaze is changed compared to the previous situation may be designated as the preconfigured situation.

The processor 120 may identify, in response to identification of a situation change of the electronic device 101, posture information of the electronic device 101 by using at least one sensor included in the sensor module 176. The processor 120 may identify posture information including a vertical vector of the flexible display 260, based on sensor data collected by an acceleration sensor and a gyro sensor included in the sensor module 176. For example, when the situation is changed to a situation in which the user's arm is maintained in a fixed state at a predetermined angle, such as when driving a vehicle or riding a bicycle, the processor 120 may identify the direction in which the flexible display 260 of the electronic device 101 is oriented according to the user's driving of a vehicle, based on posture information including a vertical vector of the flexible display 260.

The processor 120 may identify a certain area in which the user's gaze is fixed and maintained on the first display area of the flexible display 260, based on situation information of the electronic device 101 and/or posture information of the electronic device 101. For example, when the situation is changed to a situation in which a user's arm is maintained in a fixed state at a predetermined angle in a first direction, such as when driving a vehicle, the processor 120 may identify a certain area of the flexible display 260, to which the user's gaze may be directed according to the first direction of the user's arm, based on posture information including a vertical vector of the flexible display 260. Further, when the identified certain area is limited to a partial area of the first display area of the flexible display 260, the processor 120 may determine the corresponding partial area as a second display area. Alternatively, when the situation is changed to a situation in which the user's arm is maintained in a fixed state at a predetermined angle in a second direction, such as when riding a bicycle, the processor 120 may identify a certain area of the flexible display 260, to which the user's gaze may be directed according to the second direction of the user's arm, based on posture information including a vertical vector of the flexible display 260. Further, when the identified certain area is limited to a partial area of the first display area of the flexible display 260, the processor 120 may determine the corresponding partial area to be a second display area.

The processor 120 may display second object information in the second display area of the flexible display 260. For example, the second object information may include a watch face screen, a user interface screen, and a display screen showing various contents, which are the same as those of the first object information displayed on the first display area. The second object information may include a screen obtained by modifying a screen of the first object information to be suitable for a size or position corresponding to a second display area different from the first display area. For example, when the second display area includes a partial flat area in the first display area, the processor 120 may display second object information including a screen corresponding to an area that is relatively narrower and flatter than the first display area. Alternatively, when the second display area includes a partial curved area in the first display area, the processor 120 may display second object information including a screen corresponding to an area that is relatively narrower and more curved than the first display area.

The processor 120 may activate the first display area or the second display area among the entire area of the flexible display 260, and may deactivate a third display area different from the first display area and the second display area among the entire area. For example, deactivation may refer to: turning off power to a screen area other than the first display area or the second display area among the entire area of the flexible display 260; not displaying the screen; or changing the brightness or color of the screen.

The processor 120 may identify area information of the first display area or the second display area of the flexible display using the bending sensor 660, and may change and display the first object information or the second object information based on the identified area information. For example, the thicknesses of wrists of various users wearing the electronic device 101 may be different from each other, and the degree of bending of the flexible display 260 may also be different from each other according to the thicknesses of the wrists of the users. For example, the flexible displays 260 may have the same total area. However, the bending degrees or bending positions of the flexible displays 260 may be different depending on the users wearing the flexible displays, and thus area segmentation of the flexible displays 260 may be differently configured. The processor 120 may configure a screen size or arrangement of the first object information or the second object information differently from the default screen configuration so as to be suitable for the area information of the first display area or the second display area of the flexible display 260, and display the same.

The processor 120 may identify movement information of the electronic device 101 using at least one sensor included in the sensor module 176, and may change and display the first object information or the second object information based on the identified movement information. For example, the processor 120 may identify movement information of the electronic device 101 based on sensor data collected by at least one of a gyro sensor, a magnetic sensor, or an acceleration sensor included in the sensor module 176, and when the identified movement information is repeated with a predetermined pattern, the processor 120 may change and display a display direction, a screen size, or an arrangement of the first object information or the second object information with respect to the default screen configuration so as to have visibility suitable for the corresponding movement.

The memory 130 may store a program and various data for controlling the overall operation of the electronic device 101. For example, the memory 130 may store instructions which, when executed, control the processor 120 to perform various operations.

The communication module 190 may have a hardware and software configuration that enables video communication, voice communication, and data communication.

The sensor module 176 may include sensors required for the processor 120 to acquire wearing state information, bending state information, situation information, or posture information of the electronic device 101. For example, the sensor module 176 may include at least one of a gyro sensor, a magnetic sensor, an acceleration sensor, a proximity sensor, or a biometric sensor. The sensor module 176 may include at least one inertial sensor (e.g., a gyro sensor and/or an acceleration sensor), and the at least one inertial sensor may perform the corresponding function in place of all or part of the bending sensor 660.

The flexible display 260 may be a hardware configuration that displays information processed in the electronic device 101. The flexible display 260 may provide an information screen to a user. The flexible display 260 may be configured as a touch screen including a touch panel.

The bending sensor 660 may measure a bending degree of the electronic device 101 or the flexible display 260. For example, the bending degree may refer to a state in which the external shape of the electronic device 101 or the flexible display 260 is changed, such as bending, folding, or rolling. The bending sensor 660 may be configured such that flexible sensors capable of measuring the bending degree of the electronic device 101 are combined with the flexible display 260 and used. For example, the bending sensor 660 may include at least one of a flex sensor, a pressure sensor, at least one inertial sensor (e.g., a gyro sensor and/or an acceleration sensor), or a Hall effect IC sensor. For example, the bending sensor 660 may include a flex sensor, and the flex sensor may detect whether the flexible display 260 is deformed according to whether a measured resistance value is changed. In addition, the flex sensor may include a plurality of sensing points arranged at a predetermined interval, and may detect a deformation curvature or a deformation position according to a numerical change collected at each sensing point. Alternatively, according to the structure of the electronic device 101, for example, in a case where the electronic device 101 includes the body 510 having a structure as shown in FIGS. 5A and 5B, the bending sensor 660 may include a Hall effect IC sensor installed at each node of the body 510, the Hall effect IC sensor may measure the proximity degree between nodes, and may detect a deformation curvature or a deformation position according to the proximity degree or position. The bending sensor 660 may include a plurality of inertial sensors (e.g., a gyro sensor and/or an acceleration sensor), and the plurality of inertial sensors are disposed at a predetermined interval inside the flexible display 260, and may detect a deformation curvature or a deformation position of the flexible display 260 on the basis of a relative posture difference of each inertial sensor.

FIG. 7 is a flowchart of a method of controlling a flexible display by an electronic device according to an embodiment.

Referring to FIG. 7, steps 710, 720, 730, and 740 may be implemented through the electronic device 101, the electronic device 102, or the electronic device 104, or the processor 120. The electronic device 101 may store instructions for executing steps 710, 720, 730, and 740 in the memory 130. At least one of steps 710, 720, 730, and 740 may be omitted, the order of some steps may be changed, or another step may be added.

In step 710, the electronic device 101 may determine a first display area of the display device 160 or the flexible display 260. For example, the electronic device 101 may determine a first display area of the flexible display 260, based at least on wearing state information of the electronic device 101 and/or bending state information of the electronic device 101.

The electronic device 101 may identify whether the electronic device 101 is being worn on a user's body using a biometric sensor or a proximity sensor included in the sensor module 176, or the fastening member 315, responsible for fastening the electronic device 101.

When it is identified that the electronic device 101 is being worn on a user's body, the electronic device 101 may identify the part of the body on which the electronic device 101 is being worn or the orientation thereof using at least one of a gyro sensor, a magnetic sensor, or an acceleration sensor included in the sensor module 176.

The electronic device 101 may identify bending state information, including area segmentation information of the flexible display 260 corresponding to the bending degree of the flexible display 260, using the bending sensor 660.

The electronic device 101 may determine a first display area of the flexible display 260 based on the identified wearing state information of the electronic device 101 and/or bending state information of the electronic device 101. For example, the electronic device 101 identifies segmented areas of the flexible display 260 based on the bending state information, and if it is determined that the electronic device 101 is being worn based on the wearing state information, the electronic device 101 may identify the part of the body of the user on which the electronic device 101 is being worn, and may identify the orientation in which the worn electronic device 101 is being worn. For example, when it is identified that the electronic device 101 is worn on the left arm of the user, based on the identified wearing state information and bending state information of the electronic device 101, the electronic device 101 may determine, as a first display area, areas corresponding to a position where the user's gaze is directed to the left from among the segmented areas of the flexible display 260. Alternatively, when it is identified that the electronic device 101 is worn on the right arm of the user, the electronic device 101 may determine, as a first display area, areas corresponding to a position where the user's gaze is directed to the right from among the segmented areas of the flexible display 260.

In step 720, the electronic device 101 may display first object information on the first display area of the flexible display 260. For example, the first object information may include a watch face screen, a user interface screen, and a display screen showing various contents. The first object information may include a screen configured to be suitable for a size or a direction corresponding to the first display area. For example, when the first display area includes a wide area in the entire area of the flexible display 260, the electronic device 101 may display first object information including a screen corresponding to a wide area. Alternatively, when the first display area includes a narrow area in the entire area of the flexible display 260, the electronic device 101 may display first object information including a screen corresponding to the narrow area. Alternatively, when the electronic device 101 is mounted on the left arm of the user, the electronic device 101 may display first object information including a screen that is usable when a user looks in the left direction. Alternatively, when the electronic device 101 is mounted on the right arm of the user, the electronic device 101 may display first object information including a screen that is usable when the user looks in the right direction.

In step 730, the electronic device 101 may determine (or identify) a second display area of the flexible display 260. For example, the electronic device 101 may perform an operation for determining the second display area in response to identification of a situation change of the electronic device 101.

The electronic device 101 may identify situation information related to a behavior pattern of a user wearing the electronic device 101, based on a pattern or learning of sensor data collected by at least one of a gyro sensor, a magnetic sensor, or an acceleration sensor included in the sensor module 176. For example, the situation information may include, as the user's behavior pattern, at least one of stopping, walking, running, riding a bicycle, driving a vehicle, or exercising using the arms. For example, the electronic device 101 may perform an operation of determining a second display area when it is identified that a previous situation changes to a preconfigured situation based on the situation information of the electronic device 101, or when it is identified that the changed situation has been maintained for a preconfigured time.

In a case where the situation change of the electronic device 101 satisfies a preconfigured situation change or the situation change is maintained for a predetermined time, the electronic device 101 may identify posture information including a vertical vector of the flexible display 260, based on sensor data collected by at least one of a gyro sensor, a magnetic sensor, or an acceleration sensor included in the sensor module 176. For example, in the case where the situation is changed to a situation in which the user's arm is maintained in a fixed state at a predetermined angle, such as when driving a vehicle or riding a bicycle, the electronic device 101 may identify the direction in which the flexible display 260 of the electronic device 101 is oriented according to the driving a vehicle of the user, based on posture information including a vertical vector of the flexible display 260.

The electronic device 101 may determine a second display area of the flexible display 260 based on the identified situation information of the electronic device 101 and/or posture information of the electronic device 101. For example, the electronic device 101 may identify a certain area, in which the user's eyes are fixed and maintained in the first display area of the flexible display 260. For example, when the situation is changed to a situation in which a user's arm is maintained in a fixed state at a predetermined angle in a first direction, such as when driving a vehicle, the electronic device 101 may identify a certain area of the flexible display 260, to which the user's gaze is directed according to the first direction of the user's arm, based on posture information including a vertical vector of the flexible display 260. Further, when the identified certain area is limited to a partial area of the first display area of the flexible display 260, the electronic device 101 may determine the corresponding partial area to be a second display area. Alternatively, in a case where the identified situation is a situation that has changed to the situation in which the user's arm is maintained in a fixed state at a predetermined angle in a second direction, such as when riding a bicycle, the electronic device 101 may identify a certain area of the flexible display 260, to which the user's gaze may be directed to according to the second direction of the user's arm, based on posture information including a vertical vector of the flexible display 260. Further, when the identified certain area is limited to a partial area of the first display area of the flexible display 260, the electronic device 101 may determine the partial area to be a second display area.

In step 740, the electronic device 101 may display second object information in the second display area of the flexible display 260. For example, the second object information may include a watch face screen, a user interface screen, and a display screen showing various contents, which are the same as those of the first object information displayed on the first display area. The second object information may include a screen obtained by modifying a screen of the first object information to be suitable for a size or position corresponding to a second display area, different from the first display area. For example, in the case where the second display area includes a partial flat area in the first display area, the electronic device 101 may display second object information including a screen corresponding to an area that is relatively narrower and flatter than the first display area. Alternatively, in the case where the second display area includes a partial curved area in the first display area, the electronic device 101 may display second object information including a screen corresponding to an area that is relatively narrower and more curved than the first display area.

FIG. 8 is an illustration of a method for identifying wearing state information by the electronic device 101 according to an embodiment.

Referring to FIG. 8, the electronic device 101 may be worn on a user's left arm 201 or the user's right arm 202. The electronic device 101 may determine the arm of the user on which the electronic device 101 is mounted, using at least one of a gyro sensor, an acceleration sensor, or a magnetic sensor included in the sensor module 176. For example, when the electronic device 101 is worn on the user's left arm 201, the acceleration value for the x-axis obtained by the acceleration sensor may have a value of “+g”, and when the electronic device 101 is worn on the user's right arm 202, the acceleration value of the x-axis obtained by the acceleration sensor may have a value of “−g”, and thus the position and the direction in which the electronic device 101 is worn may be distinguished.

FIG. 9A is an illustration of the bending sensor 660 of the electronic device 101 according to an embodiment. FIG. 9B is an illustration of the bending sensor 660 of the electronic device 101 according to an embodiment.

Referring to FIGS. 9A and 9B, FIG. 9A illustrates the bending sensor 660 of the electronic device 101 implemented in the flexible display 260, and FIG. 9B illustrates the bending sensor 660 of the electronic device 101 implemented in the body 510.

The flexible display 260 of the electronic device 101 may be implemented in combination with the bending sensor 660. For example, the bending sensor 660 may be a flex sensor capable of measuring resistance values differently according to the degree of bending. The flex sensor may detect whether the flexible display 260 is deformed, according to whether the measured resistance value changes. In addition, the flex sensor may include a plurality of sensing points 665 disposed at a predetermined interval, and may detect a deformation curvature or a deformation position according to a numerical change collected at each sensing point 665.

In a case where the body 510 of the electronic device 101 is implemented as a plurality of segmented nodes 511 and hinges 512 connecting the nodes 511 at the bottom of the flexible display 260, each node 511 may be implemented to include a Hall effect IC sensor. For example, the Hall effect IC sensor included in each of the nodes 511 of the body 510 may measure the proximity degree of nodes 511, and may detect a deformation curvature or a deformation position according to the proximity degree or position. For example, depending on whether a distance measured between nodes 511 of the body 510 is Δd1 or Δd2, the deformation curvature or the deformation position of the electronic device 101 may be detected.

FIG. 10 is an illustration of a method for dividing an area of a flexible display by the electronic device 101 according to an embodiment.

Referring to FIG. 10, the electronic device 101 may be divided into a plurality of areas 261, 262, and 263 corresponding to a bending degree of the flexible display 260, based on sensor data obtained by a bending sensor 660. For example, when the electronic device 101 is worn on the wrist of the user's body, the flexible display 260 may be bent according to an upper portion of the wrist (for example, the manner in which a watch is worn) and a curve along the side of the wrist. The area of the flexible display 260 may be divided by measuring the bending degree using the bending sensor 660. For example, assuming that the electronic device 101 is worn on the user's left arm, an area of the flexible display 260 corresponding to a first position of the left wrist (for example, the left direction from the wrist) is divided into a first area 261, an area of the flexible display 260 corresponding to a second position of the left wrist (e.g., the upper part of the wrist) may be divided into a second area 262, and an area of the flexible display 260 corresponding to a third position of the left wrist (e.g., the right direction from the wrist) may be divided into a third area 263.

FIG. 11A is an illustration of a method for determining a first display area of the flexible display 260 by the electronic device 101 according to an embodiment. FIG. 11B is an illustration of a method for determining a first display area of the flexible display 260 by the electronic device 101 according to an embodiment.

Referring to FIGS. 11A and 11B, FIG. 11A illustrates the electronic device 101 worn on the left arm of a user's body, and FIG. 11B illustrates the electronic device 101 worn on the right arm of the user's body.

When the electronic device 101 is worn on the user's left wrist, the user's gaze may be directed to the second area 262 and the third area 263 among the plurality of areas 261, 262, and 263 of the flexible display 260. For example, the electronic device 101 may determine, as a first display area 1161 a, the second area 262 and the third area 263 to which the user's gaze may mainly be directed. For example, the electronic device 101 may activate the second area 262 and the third area 263 included in the first display area 1161 a so as to display an information screen (e.g., first object information), and may deactivate the first area 261 excluded from the first display area 1161 a. For example, power of the deactivated first area 261 may be shut off, a screen may not be displayed, or the brightness or color of the screen may be changed. A screen different from the information screen may be displayed on the deactivated first area 261. For example, the screen different from the information screen may display a preconfigured or fixed image, such as a part of a watch shape or a strap, or an aesthetically pleasing image.

When the electronic device 101 is worn on the user's right wrist, the user's gaze may be directed to the first area 261 and the second area 262 among the plurality of areas 261, 262, and 263 of the flexible display 260. For example, the electronic device 101 may determine the first area 261 and the second area 262, to which the user's gaze may mainly be directed, as the first display area 1161 b. For example, the electronic device 101 may activate the first area 261 and the second area 262 included in the first display area 1161 b so as to display an information screen (e.g., first object information), and may deactivate the third area 263 excluded from the first display area 1161 b.

FIG. 12 is an illustration of a method for identifying posture information by the electronic device 101 according to an embodiment.

Referring to FIG. 12, the electronic device 101 may measure a vertical vector perpendicular to the x-y plane of an electronic device 101, using an acceleration sensor 1260 mounted parallel to the flexible display 260. For example, the vertical vector may have a range from −90 degrees to +90 degrees. For example, when the vertical vector is −90 degrees, the electronic device 101 may identify that the flexible display 260 is in a flat state and is facing the ground. Alternatively, when the vertical vector is 0 degrees, the electronic device 101 may identify that the flexible display 260 is in the vertical state. Alternatively, when the vertical vector is +90 degrees, the electronic device 101 may identify that the flexible display 260 is in the flat state and facing upwards. According to various embodiments, the electronic device 101 may configure a reference gaze posture (e.g., a reference vertical vector), from which the user views the electronic device 101, using the vertical vector Z of the flexible display 260. For example, the electronic device 101 may configure, as a reference gaze posture value, a vertical vector of the flexible display 260 when the user generally looks at the electronic device 101 according to a wearing position or a wearing orientation of the electronic device 101. When the vertical vector of the flexible display 260 is different from the reference gaze posture value, the electronic device 101 may identify that the gaze posture of the user looking at the electronic device 101 has changed. In addition, when it is identified that the gaze posture of the user has changed, the electronic device 101 may change a display area of the flexible display 260 based on the vertical vector of the flexible display 260 at the corresponding time point. For example, the electronic device 101 may provide a configuration interface that enables a user to configure the reference gaze posture of the electronic device 101, induce the user to look the electronic device 101 naturally through the configuration interface, and configure, as the reference gaze posture value, the vertical vector of the flexible display 260 at the corresponding time point. The configuration interface may be provided as part of a configuration menu of the electronic device 101, and the configuration interface may be provided according to the user's menu selection. Alternatively, the configuration interface may be provided during an initial configuration process of the electronic device 101 upon first execution of the electronic device 101. The electronic device 101 may configure a plurality of different gaze posture values for each user situation by using a vertical vector identified for each user situation.

FIG. 13A is an illustration of a method for determining a second display area of a flexible display by the electronic device 101 according to an embodiment. FIG. 13B is a diagram 1300 b for illustrating a method for determining a second display area of a flexible display by an electronic device according to various embodiments.

Referring to FIGS. 13A and 13B, when, for example, the electronic device 101 is worn on the left arm of a user's body, FIG. 13A illustrates an example in which the user's gaze is directed to the third area 263 of the flexible display 260 from the perspective of the user's gaze, and FIG. 13B illustrates an example in which the user's gaze is directed to the third area 263 of the flexible display 260 from the perspective of the user's wearing of the electronic device.

The electronic device 101 may be worn on the wrist of the user's left arm 201, and the user's gaze may be concentrically directed to the inside of the wrist of the user's left arm 201. For example, the electronic device 101 may configure, as a reference gaze posture value, a vertical vector of the flexible display 260 when the user generally looks at the electronic device 101. For example, the vertical vector of the flexible display 260 may have a value of about 45 degrees when the user's gaze is located in the second area 262 and the third area 263 of the flexible display 260 while the user is wearing the electronic device 101 on the wrist of the left arm 201, and the electronic device 101 may configure, as the reference gaze posture value, a value of the vertical direction vector of about 45 degrees. When the situation information of the electronic device 101 is changed to a preconfigured situation and the vertical vector of the flexible display 260 has a value of about 90 degrees, different from the value of about 45 degrees, which is a reference gaze posture value, the electronic device 101 may identify that the user's gaze posture has changed. When the vertical vector of the flexible display 260 has a value of approximately 90 degrees, the electronic device 101 may identify that the user's gaze is concentrically directed to the third area 263 of the flexible display 260, and may determine the third area 263, to which the user's gaze is concentrically directed, to be a second display area 1362. For example, as illustrated in FIG. 11A, the electronic device 101 may determine that the first display area 1161 a includes the second area 262 and the third area 263 of the flexible display 260. In addition, when the user's posture is changed and the user's gaze is concentrically directed to the third area 263, the electronic device 101 may determine the third area 263 of the flexible display 260 to be a second display area 1362. For example, when a display area of the flexible display 260 is switched from the first display area 1161 a to the second display area 1362, the electronic device 101 may activate only the third area 263 included in the second display area 1362 so as to display an information screen 1365 (for example, second object information), and may deactivate the first area 261 and the second area 262 excluded from the second display area 1362.

FIG. 14A is an illustration of a method for determining a second display area of a flexible display by the electronic device 101 according to an embodiment. FIG. 14B is an illustration of a method for determining a second display area of a flexible display by the electronic device 101 according to an embodiment.

Referring to FIGS. 14A and 14B when, for example, the electronic device 101 is worn on the left arm of the user's body, FIG. 14A illustrates an example in which the user's gaze is directed to the second area 262 of the flexible display 260 from the perspective of the user's gaze, and FIG. 14B illustrates an example in which the user's gaze is directed to the second area 262 of the flexible display 260 from the perspective of the user's wearing of the electronic device.

The electronic device 101 may be worn on the wrist of the user's left arm 201, and the user's gaze may be concentrically directed to the upper part of the wrist of the user's left arm 201. For example, the electronic device 101 may configure, as the reference gaze posture value, a value of about 45 degrees, which is a vertical vector when the user's gaze is located in the second area 262 and the third area 263 of the flexible display 260 while the user is wearing the electronic device 101 on the wrist of the left arm 201. The electronic device 101 may identify that the user's gaze posture has changed when the situation information of the electronic device 101 is changed to a preconfigured situation, and the vertical vector of the flexible display 260 closes to a value of about 0 degrees, which is different from the value of about 45 degrees, which is the reference gaze posture value. When the vertical vector of the flexible display 260 has a value of about 0 degrees, the electronic device 101 may identify that the user's gaze is concentrically directed to the second area 262 of the flexible display 260, and may determine the second area 262 to which the user's gaze is concentrically directed, to be a second display area 1462. For example, as illustrated in FIG. 11A, the electronic device 101 may determine that the first display area 1161 a includes the second area 262 and the third area 263 of the flexible display 260. In addition, when the user's posture is changed and the user's gaze is concentrically directed to the second area 262, the electronic device 101 may determine the second area 262 of the flexible display 260 to be a second display area 1462. For example, when the display area of the flexible display 260 is switched from the first display area 1161 a to the second display area 1462, the electronic device 101 may activate only the second area 262 included in the second display area 1462 so as to display an information screen 1465 (for example, second object information), and may deactivate the first area 261 and the third area 263 excluded from the second display area 1462.

FIG. 15 is a flowchart of a method of controlling a flexible display by an electronic device according to an embodiment.

Referring to FIG. 15, steps 1510, 1520, 1530, 1540, and 1550 may be implemented through the electronic device 101, the electronic device 102, or the electronic device 104 or the processor 120. The electronic device 101 may store instructions for executing steps 1510 to 1560 in the memory 130. At least one of step 1510 to 1560 may be omitted, the order of some steps may be changed, or another step may be added.

In step 1510, the electronic device 101 may identify whether the electronic device 101 is being worn on a user's body. For example, the electronic device 101 may identify whether the electronic device 101 is being worn on the user's body using a biometric sensor or a proximity sensor included in the sensor module 176, or the fastening member 315 that is responsible for fastening the electronic device 101.

In step 1520, the electronic device 101 may identify bending state information of the electronic device 101. For example, the electronic device 101 may identify bending state information including area segmentation information of the flexible display 260, corresponding to the bending degree of the flexible display 260, using the bending sensor 660.

In step 1530, the electronic device 101 may identify wearing state information of the electronic device 101. For example, the electronic device 101 may determine a position of the body at which the electronic device 101 is being worn or an orientation thereof by using a gyro sensor, a magnetic sensor, and an acceleration sensor included in the sensor module 176. When the wearing state information including the wearing position or the wearing orientation of the electronic device 101 is identified, the electronic device 101 may perform step 1540, and when the wearing state information is not identified, the electronic device 101 is in a standby state until the wearing state information is identified.

In step 1540, the electronic device 101 may determine a first display area of the flexible display 260 based on the identified wearing state information of the electronic device 101 and/or bending state information of the electronic device 101. For example, the electronic device 101 may identify segmented areas of the flexible display 260 based on the bending state information, and if the electronic device 101 is determined to be in a state of being worn by the user based on the wearing state information, the electronic device 101 may identify the position of the user's body on which the electronic device 101 is being worn, and may identify the orientation of the electronic device 101 being worn by the user. For example, when it is identified that the electronic device 101 is worn on the left arm of the user, based on the identified wearing state information and bending state information of the electronic device 101, the electronic device 101 may determine, as a first display area, areas corresponding to the location where the user's gaze is directed to the left among the segmented areas of the flexible display 260. Alternatively, when it is identified that the electronic device 101 is worn on the right arm of the user, the electronic device 101 may determine, as the first display area, areas corresponding to the location where the user's gaze is directed to the right among segmented areas of the flexible display 260.

In step 1550, the electronic device 101 may display first object information on the first display area of the flexible display 260. For example, the first object information may include a watch face screen, a user interface screen, and a display screen showing various contents. The first object information may configure a screen to be suitable for a size or a direction corresponding to the first display area. For example, when the first display area includes a wide area in the entire area of the flexible display 260, the electronic device 101 may display first object information including a screen corresponding to the wide area. Alternatively, when the first display area includes a narrow area in the entire area of the flexible display 260, the electronic device 101 may display first object information including a screen corresponding to the narrow area. Alternatively, when the electronic device 101 is mounted on the left arm of the user, the electronic device 101 may display first object information configured as a screen suitable for a user looking in the left direction. Alternatively, when the electronic device 101 is mounted on the right arm of the user, the electronic device 101 may display first object information configured as a screen suitable for the user looking in the right direction.

In step 1560, the electronic device 101 may identify whether the user has taken off the electronic device 101. When the electronic device 101 is taken off, the electronic device 101 may end display control of the flexible display 260. If the electronic device 101 is not taken off, the electronic device 101 may perform step 1610 in FIG. 16 as a subsequent operation.

FIG. 16 is a flowchart of a method of controlling a flexible display by an electronic device according to an embodiment.

Referring to FIG. 16, steps 1610, 1620, 1630, 1640, 1650, and 1660 may be implemented through the electronic device 101, the electronic device 102, or the electronic device 104, or the processor 120. The electronic device 101 may store instructions for executing steps 1610 to 1660 in the memory 130. At least one of steps 1610 to 1660 may be omitted, the order of some steps may be changed, or another step may be added.

Steps 1610 to 1660 may be steps that are subsequently performed when the electronic device 101 is not taken off in step 1560 of FIG. 15.

In step 1610, the electronic device 101 may identify a change in the situation of the electronic device 101. For example, the electronic device 101 may identify situation information related to a behavior pattern of a user wearing the electronic device 101 based on a pattern or learning of sensor data collected by at least one of a gyro sensor, a magnetic sensor, or an acceleration sensor included in the sensor module 176. For example, the situation information may include, as a user's behavior pattern, at least one of stopping, walking, running, riding a bicycle, driving a vehicle, or exercising using the arms.

In step 1620, the electronic device 101 may identify that the situation of the electronic device 101 has changed when it is identified that the previous situation has changed to a preconfigured situation based on the situation information of the electronic device 101, or when it is identified that the changed situation is maintained for a preconfigured period of time. The electronic device 101 performs step 1630 when it is identified that the situation change of the electronic device 101 satisfies a preconfigured situation change or the situation change is maintained for a predetermined period of time. Otherwise, the electronic device 101 may be in a standby state and proceed to step 1610 until the situation change of the electronic device 101 satisfies the preconfigured situation change.

In step 1630, when the situation change of the electronic device 101 satisfies a preconfigured situation change or when the situation change is maintained for a predetermined period of time, the electronic device 101 may identify posture information including a vertical vector of the flexible display 260, based on sensor data collected by an acceleration sensor or a gyro sensor included in the sensor module 176. For example, when the situation of the electronic device 101 is changed to a situation in which the user's arm is maintained in a fixed state at a predetermined angle, such as when driving a vehicle or riding a bicycle, the electronic device 101 may identify the direction in which the flexible display 260 of the electronic device 101 is oriented according to the user driving a vehicle, based on posture information including the vertical vector of the flexible display 260. If the posture information of the electronic device 101 is identified, the electronic device 101 may perform step 1640, and, if the posture information is not identified, the electronic device 101 may proceed to step 1610.

In step 1640, the electronic device 101 may determine a second display area of the flexible display 260 based on the identified situation information of the electronic device 101 and/or posture information of the electronic device 101. For example, the electronic device 101 may identify a certain area in which the user's gaze is fixed and maintained in a first display area of the flexible display 260. For example, when the identified situation is changed to a situation in which the user's arm is maintained in a fixed state at a predetermined angle in the first direction, such as when driving a vehicle, the electronic device 101 may identify a certain area of the flexible display 260 to which the user's gaze can be directed according to the first direction of the user's arm, based on the posture information including the vertical vector of the flexible display 260. Further, when the identified certain area is limited to a partial area in the first display area of the flexible display 260, the electronic device 101 may determine the partial area as a second display area. Alternatively, when the identified situation is changed to a situation in which the user's arm is maintained in a fixed state at a predetermined angle in a second direction, such as when riding a bicycle, the electronic device 101 may identify a certain area of the flexible display 260 to which the user's gaze can be directed according to the second direction of the user's arm, based on the posture information including the vertical vector of the flexible display 260. Further, when the identified certain area is limited to a partial area in the first display area of the flexible display 260, the electronic device 101 may determine the corresponding partial area to be a second display area.

In step 1650, the electronic device 101 may display second object information in the second display area of the flexible display 260. For example, the second object information may include a watch face screen, a user interface screen, and a display screen showing various contents, which are the same as the first object information displayed on the first display area. The second object information may include a screen obtained by modifying a screen of the first object information to be suitable for a size or position corresponding to a second display area different from the first display area. For example, when the second display area includes a partial flat area in the first display area, the electronic device 101 may display second object information configured as a screen corresponding to an area that is relatively narrower and flatter than the first display area. Alternatively, when the second display area includes a partial curved area in the first display area, the electronic device 101 may display second object information configured as a screen corresponding to an area that is relatively narrower and more curved than the first display area.

In step 1660, the electronic device 101 may identify whether the user has taken off the electronic device 101. When the electronic device 101 has been taken off, the electronic device 101 may end display control of the flexible display 260. If the electronic device 101 has not been taken off, the electronic device 101 may perform step 2110 in FIG. 21 as a subsequent operation.

FIG. 17 is an illustration in which the electronic device 101 controls a flexible display according to an embodiment.

Referring to FIG. 17, a user may wear the electronic device 101 on the wrist of the user's right arm 202, and the user may be in a state of holding a steering wheel 1701 of a vehicle with both hands of the left arm 201 and the right arm 202 while driving the vehicle.

For example, the electronic device 101 may identify that the electronic device 101 is located on the right side of the user and determine, as a first display area, a first area 261 and a second area 262 of the flexible display 260, in which the user's gaze is mainly located while the electronic device 101 is located on the right side of the user, and may display screen information on the determined first display area.

Thereafter, when the user's behavior pattern is changed to a vehicle-driving state, the electronic device 101 may recognize that the situation of the electronic device 101 is changed to the vehicle-driving state, and may identify posture information of the electronic device 101 including the vertical vector of the flexible display 260 in a driving a vehicle situation. The electronic device 101 may identify that the first area 261 of the flexible display 260 corresponding to the side of the user's wrist is located in the user's gaze, based on posture information of the electronic device 101, and may change a display area of the flexible display 260 from the previous first display area to a second display area 1762 including only the first area 261.

FIG. 18 is an illustration in which the electronic device 101 controls a flexible display according to an embodiment.

Referring to FIG. 18, a user may wear the electronic device 101 on the wrist of the user's right arm 202, and the user may be in a state of holding a steering wheel 1801 of a bicycle with both hands of the left arm 201 and the right arm 202 while driving the bicycle. For example, the electronic device 101 may identify that the electronic device 101 is located on the left side of the user and determine, as a first display area, a second area 262 and a third area 263 of the flexible display 260, in which the user's gaze is mainly located while the electronic device 101 is located on the left side of the user, and may display screen information on the determined first display area.

Thereafter, when the user's behavior pattern is changed to a bicycle-riding state, the electronic device 101 may recognize that the situation of the electronic device 101 is changed to the bicycle-riding state, and may identify posture information of the electronic device 101 including the vertical vector of the flexible display 260 in the riding a bicycle situation. The electronic device 101 may identify that the second area 262 of the flexible display 260 corresponding to the upper side of the user's wrist is located in the user's gaze, based on the posture information of the electronic device 101, and may change a display area of the flexible display 260 from the previous first display area to a second display area 1862 including only the second area 262.

FIG. 19 is a flowchart of a method of controlling a flexible display by an electronic device according to an embodiment.

Referring to FIG. 19, steps 1910, 1920, 1930, 1940, 1950, 1960, and 1970 may be implemented through the electronic device 101, the electronic device 102, or the electronic device 104, or the processor 120. The electronic device 101 may store instructions for executing steps 1910 to 1970 in the memory 130. At least one of steps 1910 to 1970 may be omitted, the order of some steps may be changed, or another step may be added.

Steps 1910 to 1970 may be steps that are subsequently performed when the electronic device 101 is determined not to have been taken off in step 1560 of FIG. 15.

In step 1910, the electronic device 101 may identify a situation change of the electronic device 101.

In step 1920, the electronic device 101 performs step 1930 when it is identified that the situation change of the electronic device 101 satisfies a preconfigured situation change or the situation change is maintained for a predetermined period of time.

Otherwise, the electronic device 101 may be in a standby state and proceed to step 1910 until the situation change of the electronic device 101 satisfies the preconfigured situation change.

In step 1930, when the situation change of the electronic device 101 satisfies a preconfigured situation change or when the situation change is maintained for a predetermined period of time, the electronic device 101 may identify posture information including a vertical vector of the flexible display 260, based on sensor data collected by an acceleration sensor or a gyro sensor included in the sensor module 176. If the posture information of the electronic device 101 is identified, the electronic device 101 may perform step 1940, and if the posture information is not identified, the electronic device 101 may proceed to step 1910.

In step 1940, the electronic device 101 may determine a second display area of the flexible display 260, based on the identified situation information of the electronic device 101 and/or posture information of the electronic device 101.

In step 1950, the electronic device 101 may identify bending state information of the electronic device 101. For example, the electronic device 101 may identify area information of the second display area of the flexible display by using the bending sensor 660. For example, the thicknesses of wrists of various users wearing the electronic device 101 may be different from each other, and bending degrees of the flexible display 260 may also be different from each other according to the thickness of the wrists of the users. For example, the total areas of the flexible displays 260 may be the same, but bending degrees or bending positions of the flexible displays 260 may be different depending on the user wearing the electronic device, and thus, area segmentation of the flexible display 260 may be configured differently. Therefore, the areas of the second display areas of the flexible displays 260 may be different from each other.

In step 1960, the electronic device 101 may display second object information in the second display area. For example, the electronic device 101 may display second object information based on the identified area information of the second display area. For example, the second object information may be configured and displayed differently from a default screen configuration in which the size or layout of a screen is arranged to be suitable for the area information of the second display area.

In step 1970, the electronic device 101 may identify whether the user has taken off the electronic device 101. If the electronic device 101 has been taken off, the electronic device 101 may end display control of the flexible display 260. If the electronic device 101 has not been taken off, the electronic device 101 may perform step 2110 in FIG. 21 as a subsequent step.

FIG. 20A is an illustration of a method for identifying a segmented area of a flexible display by the electronic device 101 according to an embodiment. FIG. 20B is an illustration of a method for identifying a segmented area of a flexible display by the electronic device 101 according to an embodiment.

Referring to FIGS. 20A and 20B, the wrist thicknesses of users are different from each other, and FIG. 20A illustrates the situation where the wrist of a user is thicker than that of FIG. 20B.

When the electronic device 101 is worn on a user's wrist, the length of the end of the strap 215 a shown in FIG. 20A and the length of the end of the strap 215 b shown in FIG. 20B may be adjusted differently depending on the thickness of a user's wrist. The area of segmented areas 261 a, 262 a, and 263 a of the flexible display 260 a shown in FIG. 20A and the area of the segmented areas 261 b, 262 b, and 263 b of the flexible display 260 b shown in FIG. 20B may be different from each other, and bending portions thereof may be different from each other.

FIG. 21 is a flowchart of a method of controlling a flexible display by an electronic device according to an embodiment.

Referring to FIG. 21, steps 2110, 2120, 2130, and 2140 may be implemented through the electronic device 101, the electronic device 102, or the electronic device 104, or the processor 120. The electronic device 101 may store instructions for executing steps 2110 to 2140 in the memory 130. At least one of steps 2110 to 2140 may be omitted, the order of some steps may be changed, or another step may be added.

Steps 2110 to 2140 may be steps that are subsequently performed when the electronic device 101 is not taken off in step 1660 of FIG. 16 or step 1970 in FIG. 17.

In step 2110, the electronic device 101 may identify movement information of the electronic device 101. For example, the electronic device 101 may identify whether the identified movement information is repeated with a predetermined pattern. When it is identified that the identified movement information is repeated with a predetermined pattern, the electronic device 101 may perform step 2120.

In step 2120, the electronic device 101 may, in response to the movement information, change and display a display direction, a screen size, or a layout of the second object information with respect to a default screen configuration, so as to have appropriate visibility.

In step 2130, the electronic device 101 may identify whether the situation of the electronic device 101 changes, and if the situation changes, the electronic device 101 may perform step 1610 in FIG. 16 as a subsequent step, and if the situation does not change, the electronic device 101 may proceed to step 2140.

In step 2140, the electronic device 101 may determine whether the user has taken off electronic device 101. If the electronic device 101 is taken off, the electronic device 101 may end display control of the flexible display 260. If the electronic device 101 is not taken off, the electronic device 101 may proceed to step 2110.

FIG. 22 is an illustration of an example in which the electronic device 101 controls a flexible display according to various embodiments.

Referring to FIG. 22, a user may wear the electronic device 101 on the wrist of the user's left arm 201 and the user may move the left arm 201. For example, the electronic device 101 may display screen information 2265 (e.g., second object information) on a third area 263 of the flexible display 260. The electronic device 101 may detect the user's movement 2210 by identifying the movement information of the electronic device 101, and if a condition of changing and displaying screen information 2265 in which the user's movement 2210 is displayed is satisfied, the electronic device 101 may change and display the screen information 2265 displayed in a direction 2262 corresponding to the user's movement 2210.

FIG. 23 is an illustration of an example in which the electronic 101 device controls a flexible display according to an embodiment.

Referring to FIG. 23, a user may wear the electronic device 101 on the wrist of the user's right arm, and the user may exercise with the arms (e.g., perform a bench press).

For example, the electronic device 101 may identify movement information of the electronic device 101 so as to detect whether the user is in a repetitive exercise state with a predetermined pattern. Further, if the user's exercise pattern satisfies a condition of changing and displaying displayed screen information, the electronic device 101 may distinguish and identify a first state 2310 of the user (e.g., a state in which the user has lifted a weight (a hold state)) and a second state 2320 (e.g., a state in which the user is raising a weight (a movement state)). The electronic device 101 may display screen information by performing display control of the flexible display 260 in the first state 2310 by default. In addition, the electronic device 101 may perform display control of the flexible display 260 in the second state 2320 by changing and displaying a display direction or a display position of the screen information, so as to have appropriate visibility corresponding to the movement information of the electronic device 101.

FIG. 24 is a flowchart 2400 illustrating an operation of controlling a flexible display by an electronic device according to various embodiments.

Referring to FIG. 24, steps 2410, 2420, 2430, 2440, 2450, 2460, 2470, 2480, and 2490 may be implemented through the electronic device 101, the electronic device 102, or the electronic device 104, or the processor 120. The electronic device 101 may store instructions for executing steps 2410 to 2490 in the memory 130. At least one of step 2410 to 2490 may be omitted, the order of some steps may be changed, or another step may be added.

In step 2410, the electronic device 101 may identify whether bending of the electronic device 101 is changed. For example, the electronic device 101 may identify whether bending of the flexible display 260 is changed by using the bending sensor 660. If it is identified that bending of the electronic device 101 is changed, the electronic device 101 may perform step 2420, and if a change in bending is not identified, the electronic device 101 may proceed to step 2490.

In step 2420, the electronic device 101 may identify whether the electronic device 101 is being worn on the user's body. If wearing of the electronic device 101 is identified, the electronic device 101 may perform step 2430. If wearing of the electronic device 101 is not identified, the electronic device 101 may proceed to step 2490.

In step 2430, the electronic device 101 may identify bending state information of the electronic device 101. For example, the electronic device 101 may identify bending state information including area segmentation information of the flexible display 260 corresponding to a bending degree of the flexible display 260, using the bending sensor 660.

In step 2440, the electronic device 101 may identify wearing state information of the electronic device 101. For example, the electronic device 101 may identify wearing state information including a wearing position or a wearing orientation of the electronic device 101 by using the sensor module 176. If the wearing state information of the electronic device 101 is identified, the electronic device 101 may perform step 2450, and if the wearing state information is not identified, the electronic device 101 may be in a standby state and proceed to step 2440 until the wearing state information is identified.

In step 2450, the electronic device 101 may determine a first display area of the flexible display 260, based on the identified wearing state information of the electronic device 101 and/or bending state information of the electronic device 101.
